'Gravity' and 'Captain Phillips' are both proving to be commercial and critical successes

Sandra Bullock revealed on the Jonathan Ross Show that while filming Gravity with George Clooney the two would rap off to songs from high school – namely "Rapper's Delight."

Bullock admitted that she still knows just about all of the words from the The Sugarhill Gang rap song. Host Jonathan Ross encouraged the actress to give the studio audience an abbreviated performance. Bullock gamely agreed but asked if she could have “some beats” to back her. With just the beats – no words – playing, the actress proved she meant it when she knew the song by heart.

How did she learn the words? A high school crush whose favorite song was “Rapper’s Delight.” "I was like, 'Next time I go to that dance, I'm going to know every word,” Bullock told Ross. “I'm going to make sure he sees me lip-syncing it, and I'm going to catch his eye, and say the words. And he's going to like me. And sadly it worked."

After Bullock vacated the coach on the Jonathan Ross Show, fellow American actor Tom Hanks sat down for an interview. When Ross asked Hanks to recreate his oversized piano “Chopsticks” performance from Big, Bullock joined the Captain Phillips star. More impressive than Hanks remembering his moves from the 1988 hit was Bullock accompanying him in high heels.

Bullocks' Gravity and Hanks' Captain Phillips were at the top of the box office last weekend, in their second and first weeks, respectively. Both films have also received glowing reviews from critics.
